Sarcodes

Sarcodes is a monotypic genus of flowering plants in the heath family (Ericaceae) native to northwest North America, containing the single species Sarcodes sanguinea, commonly called the snow plant or snow flower. It is a parasitic plant that derives sustenance and nutrients from mycorrhizal fungi that attach to tree roots. Lacking chlorophyll, it is unable to photosynthesize. Ectomycorrhizal (EM) symbioses involve a mutualism between a plant root and a fungus; the plant provides fixed carbon to the fungus and in return, the fungus provides mineral nutrients, water, and protection from pathogens to the plant. The snow plant takes advantage of this mutualism by tapping into the network and stealing sugars from the photosynthetic partner by way of the fungus. This is known as mycoheterotrophy. The snow plant is host-specific and can only form relationships with the ectomycorrhizal Basidiomycete Rhizopogon ellenae.

The plant's aboveground tissue is its inflorescence, a raceme of bright scarlet red flowers wrapped in many strap-like, pointed bracts with fringed edges, themselves bright red to orange in color.
